An apparatus, system, and method allow for capping processor utilization
in a computer system. The processors are typically central processing
units (CPUs) under control of a system scheduler. The system scheduler
controls which of the CPUs will run specific processes. The processes may
run according to a predefined priority assigned to each of the
processors. A processor bandwidth waster includes a software routine that
operates as an infinite loop in one or more of the CPUs. The bandwidth
waster may have the highest priority of any process in the computer
system such that the bandwidth waster always runs on the CPUs unless a
specific action is taken to turn off, or stop, the bandwidth waster. Data
are gathered from the CPUs, including time of operation of any bandwidth
waster, and the gathered data are used to compute a bill for operation of
the computer system.
